The jet/interstellar medium interaction and the radiation properties of extragalactic jets

Résumé

The origin of the synchrotron radiation from extragalactic jets is shown to be the interaction between the jet and the insterstellar medium.This result is derived from a synthesis of available observationswhich strongly indicates that the one-sidedness is an intrinsic asymmetry. A plausible theoretical scheme is established and leads to the conclusion that the visible jet is interacting {\it less} with the interstellar medium than the invisible one (counterjet), contrary to a first intuition. The density asymmetry of the insterstellar medium required by the theory is in agreement with the observations. This model does not only account for one-sidedness of extragalactic radiosources but more broadly for double sources with no or two visible jets, for the small number of optical jets, and for some other properties of radiosources.
